Can I rebuild a vintage sled that came in boxes? Rare Harley Davidson snowmobile project begins!

Challenge accepted. Can this vintage, super rare, Harley Davidson snowmobile be put back together and run again! This 1974 440cc Harley came in boxes! I need to puzzle this back together. Most of the parts are there except for the CDI and a super hard to get piston!
Will this sled run again? Follow along to find out!

Nice! When the Harley is running we need to see a drag race between it and the Twister. Preferably with someone on each machine....Lol!

Yes preferably!! Although the other way would make things interesting.
